Features: 12V is generally used in cars, 24V is generally used in trucks, and 48V and 60V are generally used in electric vehicles. Electrical rated voltage available range: 200-240V, 100-120V. Safe range of input voltage of our inverter: 12V: 9.8-15V 8 security protection functions: Reverse Polarity Protection Low Input Voltage Protection High Input Voltage Protection Overcurrent Protection Short circuit protection Over temperature protection Overload Protection Internal Fuse Note: In order to make this inverter work better, it is recommended to use a power battery of 50AH or more. Connect the inverter to the battery and plug the AC device into the inverter. Please do not leave the power inverter in the ON position while your car is in motion. When using electrical appliances, it is recommended to use a car cigarette lighter below 150W, and directly connect the battery above 150W. It is normal for the inverter to heat up during use. For best use, place the inverter on a flat surface. The workplace should meet the following criteria: 1. Keep it dry, do not let the inverter touch water or other liquids, keep the inverter away from moisture or water. 2. Cool environment, keep the temperature between 0 degrees Celsius and 40 degrees Celsius. Do not place the inverter next to cooling vents or other equipment. Try to avoid direct sunlight on the inverter.
